Do heucherella need to go in the greenhouse for the winter please?
Hi Daphne
All heucbera heucherella and tiarella are very hardy to -20 c so shouldn’t be a problem there, however some people find they get water logged in winter
They do not like water logging at all
So make sure they are well drained
If that is taken care of there shouldn’t be any issues leaving outside all winter
We leave our out all winter !
Hope this helps
Kind regards Vicky
